Wow, you exceeded the number of package names this APT is capable of.Problem with MergeList [file]The package lists or status file could not be parsed or opened.

You have more than 65,535 packages available from your installed sources, and Cydia cannot handle this many. Go to Manage -> Sources on iPhone and iPod touch (or Sources on iPad), tap "Edit" at top right, and remove some sources. It's recommended to keep the stock repositories (BigBoss, Cydia/Telesphoreo, Dev Team, ModMyi and ZodTTD/MacCiti).

Just an update to help people finding this thread via Google: if some sources seem to not have a "remove" button when you try to remove them, that usually means they were installed as packages. Go to Manage -> Packages on iPhone/iPod touch (or to Installed on iPad), find the package with the source's name, and uninstall that package.

You installed too many repos, which ended up causing your device to have to deal with so many packages that it just can't handle it. Go to Manage and then Sources inside Cydia and delete some repos (but don't delete the stock ones: Telesphoreo, BigBoss, ModMyi, Dev Team and ZodTTD)

Well, in my case i ran into this situation and went ahead and got rid of a few sources and still the same problem. I would erase two iphonemodding files, restart cydia and run into the same problem and the same files kept showing up. I decided to give it the proper medicine (i did not want to do another restore after so much work customizing the phone) and did a full restore and ran the evasi0n 1.3 version of the jailbreak and now my iphone 5 is free of that annoying situation.

The problem with this is quite simple:
because the bigboss' repo has become so big it is now over the limit cydia can handle which is causing it to crash.
if you delete the bigboss' repo it won't have problems reading it and coming back with errors that there is too many package names in it.
untill bigboss' repo is cut down to size and maybe even and second repo for the ever expanding of it you will continue to get the same errors with reading the repo.

because the answers already given dont fix the problem is keeping the bigboss' repo installed, the problem is with bigboss' repo itself.
if you uninstall it you wot get the errors from it and you can check back to see if it has been fixed now and ten as the repo is readily available in cydia

everyone I know is having the same issue with bigboss' repo, most people that jailbreak prob don't even know about this site as they prob paid some guy in a shop to jailbreak their phone for them.

the only fix I've found is to delete bigboss' repo for the time being.
if you actually read the error cydia tells you the problem is with bigboss' repo and that it is too big.
can you not read like the other people that have commented...?

yeah I can read that an I don't have any piracy repos I support other people that release tweaks as I expect the support back (even though I make tweaks for fun, it takes my time up and it's nice to be appreciated for my time)

read the error cydia gives you it tells you that bigboss' repo exceeds the APT source limit so it can't read them all quite simple.

The reason it prints BigBoss's repo is because the number of packages in repos that were indexed prior to BigBoss have almost reached the limit, and while indexing BigBoss, APT hits the limit. Remove another repo (seriously, any repo other than BigBoss) and depending on the number of packages in it, the problem will be solved.

because if you read all the info on the screen when you refresh your cydia sources it tells you which source it is loading and in what order, then you get the repeated source download info cramp then another source loading etc.

@adam0c Perhaps you have some piracy repositories installed that you don't know are piracy repositories? The default sources (BigBoss, Cydia/Telesphoreo, Dev Team, ModMyi and ZodTTD/MacCiti) collectively have about 41 thousand packages available, and Cydia's limit is about 65 thousand. You're unlikely to be able to find enough non-default legitimate repositories to add up to having an extra 24 thousand packages available (I've tried).

BigBoss really isn't the problem here. If you only have the default sources installed, you won't run into this error message.

BigBoss was the problem the whole time why come you guys didn't tell me this earlier instead I'm going through and Internet looking for answers and y'all keep closing my questions and saying to much info and bs when I ask a shorter question y'all don't understand what I'm talking about

BigBoss is NOT the problem. Having stock repos alone will not exceed the 65535 package limit. My iPhone, my wife's iPhone, my iPod and my son's iPad all attest to this. You're pirating, you're caught, you're covering your ass. You're just doing it very poorly. Good day to you sir.
